Answer:
A
Step-by-step explanation:
You can multiply both sides on an equation by the reciprocal to cancel the fraction on the first side.
Cross multiplication is applied here.
It would be answer choice A or 5
Answer:
You would expect 807 babies to weigh between 3 and 6 pounds.
Step-by-step explanation:
We are given that
Mean,
pounds
Standard deviation,
pounds
n=1500
We have to find how many would you expect to weigh between 3 and 6 pounds.
The weights for newborn babies is approximately normally distributed.
Now,





Number of newborn babies expect to weigh between 3 and 6 pounds
=
A = l x w
l = w+14
792 = w +14 x w
792 = w² +14w
w² +14w-792=0
w= -36 w=22
You can't have a negative length so the width = 22
Length = 22+14
Length = 36 inches
